Abstract
Twenty aphasic and twenty control subjects were examined on two versions of a pantomime recognition and a verbal recognition test; one version containing response choices conceptually/semantically related to target responses, the other containing unrelated response choices. The aphasic group was inferior to controls on the pantomime and verbal recognition tests, although the magnitude and consistency of the differences between aphasics and controls were greater for the pantomime test. The presence of conceptually/semantically related response choices on the pantomime recognition test significantly reduced test scores of aphasic patients, and this reduction was related to the magnitude of the effect of response choice relatedness on their verbal recognition test performance. The findings are consistent with an interpretation of aphasia as an impairment of a central symbolic ability which can affect processing for meaning in both verbal and nonverbal modes of communication.
